“The two ETFs saw their trade halted for six minutes around noon Tuesday,” according to the report. “The Nasdaq lists the issue as an Individual Security Volatility Trading Pause, which means ‘Trading has been paused in an Exchange-Listed issue that experiences a price change of 10% or more within a rolling 5 minute period of time.’ By 12:08 both had resumed trading; VRD was down 37% and EMCD was down 9.3%.”

“Unlike last Wednesday’s Knight mishaps, today’s ‘low prints’ in those two ETFs appear to be ‘clearly erroneous’ trades and are likely to be amended,” said Paul Weisbruch at Street One Financial in an email Tuesday.
